Hi everybody, this is my first post. I have an '89 Accord LX-i with 366,000 miles on it, and it has developed a problem with the A/C. What happens is, the A/C blows cold air for a while, the compressor cycles on and off normally. But eventually, the compressor will cycle off and just never come back on until a half hour or so. Today, I drove around until the compressor kicked off for good, then I removed the glovebox, unplugged the evaporator thermostat and jumped the connector with a wire. The compressor still did not come back on. Next, I unplugged the compressor clutch relay and jumped it, still no luck. Then I bypassed the pressure sensor, thinking for sure that had to be the problem. The compressor still wouldn't kick on.
The strange thing is, the condensor fan doesn't work (bad fan motor), so I figured that maybe since the condensor wasn't getting enough airflow through it, the pressure in the high side line was getting too high, so the pressure sensor was kicking off the compressor until the pressure lowered. However, even by bypassing the pressure sensor with a jumper wire, nothing changed. There went that theory. My next step is to check for power at the compressor clutch. Does anybody have any similar experiences they could share? Thanks!
